Application led July 5, 1927.. Serial No. 203,475.

This invention relates toy beaters such as used in the manufacture of paper and the like, one of the objects being to providea heater of the back-falltype utilizing a stationary concave of increased capacity, there being combined with this concave a beating cylinder which can be adjusted relative to the concave in any direction, thus to com-` pensate for wear. and maintain the cooperating parts at maximum eiliciency,

'A further object is to mount the beating cylinder .in a novelmanner so that the desired adjustment thereof can be effected readily.A

`With the foregoing and other objects which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In S,the accompanying drawings, 'the preferred form of the invention has been shown'. y

In said drawings,

Figure 1 is a plan view of the structure constituting the present invention. p

Figure 2 is a side elevation thereof.

Fi rc 3 is an enlarged vertical section through the beater cylinder, its concave and adjacent parts.L j

. Figure 4 is a section on line 4-44, Figure 2.l`

Referring toy the figures by characters of refe-rence 1 designates a trough or tub of the usual shape and size provided with a central partition 2 at one side of which is locatedthe beating cylinder and concave constituting the present invention. As shown particularly in Figure 3 the concave can vbe cast in a single piece of hard-steel, this concave 1 being formed with integral blades 2 .disposed radially on theconcave surface and of ,uniform height When formed in'a single lcasting the vconcave lhas a bottom extension 3 at the lower end thereof while the upper end of the concave has an, inclined apron l4 integral therewith. This apron is adapted to be bolted as at 5 to an inclined plate 6, the space below tht apron and plate `and back of the concave being-filled with concrete as shown at7.' An

,inclined block 8 can arranged on the extension 3 for directing the fibrous material ior pulp upwardly to the proper level to lpass over the blades. It is to be' understood that itepreferred the concave can be built up in the customary manner' insteadof casting it in yone piece with the blades. A built-up concave is so well known in the art that it has not been deemed necessar to describe or illustrate the same in detail. be stated that it is formed of blades interposdlbetween wooden strips, the parts being held firmly together by suitable means provided for that purpose.

Heretofore concaves havel the blades located solely in a smallnclustcr at .the bottom portion thereof. In the present-instance the seric's of blades is extended from the bottom to the top Yof the concave thereby greatly increasing the capacity of the beater and consequently reducing' the cost of producing the pulp. Asit is essential that the cylinder be adjusted relative to all .of the blades of the concave, it has 4been necessary to provide a cylinder which canV be adjusted both horizontally and vertically or substantially vertically. For this purpose there is provided at each side of the trough or tub a pair of I standards 9 and 10. Fulcrumed' in the standard 9 is a'lever 11 havin 12 on. which is slidably mounted a bearing 13. To this bearing is connected a threaded rod 14 engaging a nut 15 mounted for rotation in an arm 16 extending upwardly from the lever. A worm gear 17 is secured to the nut 15 and rotates therewith, any suitable means being employed for holding they nut against longitudinal movement. "A' transverse shaft 18 extends across the trough or tub and is j journaled at its ends in the arms 16 at the two sides of the machine. Worms 19 are 'carried .by the end portions of this' shaft' and mesh withthe respective gears 17. A

Vhand wheel 20 or the like can be provided t need only been vmade with i soA a guideway i loo for rotating shaft 18 and itwill be apparent that when this shaft is rotated the two rods 14 willl bc moved longitudinally simul taneously so as to'shift the'bearings 13 in either direction along the guideways 12.

' Those ends of thelevers llrem'ote from the arms 16 are pivotally andu slidably con.- nected as at y21 to rods 22'supported in the standards 10. The upper ends of these rods are screw threaded as at 23 and are slidably mounted, any suitable means beingprovidedv for holding each rod against rotation. For l yau example a screw 24 can be extended into keyway 25 in the rod. e A nut-1n the form of afworm gear26 engages the threaded portion 23 of each rodvand these worm gears mesh with Worms 2:( carried, by the end portions of a transverse shaft` 28 journaled in a brackets 29 at the upper ends of standards E10.'- A hand wheel 3() or the like may be atof this cylindrical beater being adapted to work close to the edges of the blades 2 and being radially disposed as ordinarily.

` -For the purpose of permitting the various I l having a series of blades extendmg from the adjustments ofthe shaft 32, openings are forrned in the walls and partition of the trough or tub. o

The beater rotates at a high speed in the usual way so that ,the pulp will be carried upwardly thereby over the blades of the concave and How downwardly over the backfall. A continuous circulation of the pulp will thus beset upand the same w1ll be quickly.'

reduced or ground to the desiredconsistency.

By,l mountingA shaft 32- in the 'manner described the cylinder can be adjustedrelative to a'll of the blades'of the concave, thereby l to compensate for wear and insure a muc more extensive and ecient cutting and grinding action than would be possible with the use of a concave such asordinarilyem loyed wherein a 'small cluster of blades is ocated beneath the cylinder. f vWhat is claimed is:
